Material examined

Holotype

IRAN: ♀, Isfahan Province, Laybid, 33º28' N, 50º42' E, 2100 m, 7 Jul. 1975, P.M. Brignoli & M. Di Rao ( MSNV).

Paratype

IRAN: 1 ♀, same data as holotype.

Diagnosis

In structure of the vulva, females of Z. medica resemble those of Z. alexandri , but differ from them and all other congeners by their unpaired, very short and robust knob-shaped (transverse oval) receptacles ( Fig. 17 D, F–H).

Description

Female (holotype)

HABITUS. See Fig. 17 A–B.

BODY LENGTH. C. 8.00 (pro- and opisthosoma are separate).

COLOUR. Whole spider pale brownish-yellow; eye tubercle brownish-black; chelicerae and distal segments of legs I–IV light reddish-brown; carapace (except clypeus) and abdomen without discernible pattern.

CARAPACE ( Fig. 17 C). 3.04 long, 2.36 wide.

EYES. AME 0.10, ALE 0.21, PLE 0.18, PME 0.17, AME–AME 0.07.

ENDOGYNE ( Fig. 17 F–H). Receptacles hemispherical to transverse oval, wider than high, separated by their width, covered by a few fine pores ( Fig. 17 D).

LEG MEASUREMENTS (holotype).

	Femur	Patella	Tibia	Metatarsus	Tarsus	Total
Palp	1.40	0.81	0.98	―	1.17	4.36
I	3.17	1.18	2.89	2.82	1.76	11.82
II	2.50	1.04	2.01	1.98	1.31	8.84
III	2.12	0.82	1.51	1.54	0.93	6.92
IV	2.82	1.11	2.42	2.37	1.30	10.02

Note

It is worth noting that Brignoli (1982) illustrated a more elongate receptacle with a stem that had distinct pores on the top, whereas the examined holotype has receptacles lacking a stem and covered with less distinct pores.

Male

Unknown.

Distribution

Known only from the type locality ( Fig. 47 ).
